Turnout section box girder production process and method for manufacturing turnout box girder
The invention relates to a turnout section box girder production process and a method for manufacturing a turnout section box girder, the turnout section box girder is provided with at least two concave turnout steel rail grooves, and a post-tensioned prestressed duct is reserved in the turnout section box girder; a normal position method is adopted for manufacturing, and the method comprises the following steps that S1, a segment outer mold is cleaned; s2, turnout section box girder steel bars are put into a mold and bound; s3, the segment core mold is hoisted in and adjusted in place; s4, hoisting and binding steel bars at the top of the box girder of the turnout section; s5, the segment top formwork is hoisted in, and the turnout steel rail channel steel formwork and the steel rail channel steel bars are aligned, adjusted and fixed; s6, the post-tensioned pre-stressed pipeline penetrates through the pipe and an end mold is installed; s7, pouring concrete and plastering; s8, tarpaulin steam temperature control curing; s9, pulling out the post-tensioned prestressed pipeline after initial setting of the concrete; and S10, demolding after the concrete strength reaches 85%, and continuing to sprinkle water for curing after demolding. The turnout section box girder can be produced, and the turnout section box girder can be obtained through section transportation and on-site splicing; the method is suitable for conditions with limited transportation conditions such as mountain rail transit.
本发明涉及道岔节段箱梁生产工艺及制作道岔箱梁的方法，道岔节段箱梁有至少两道内凹的道岔钢轨槽，道岔节段箱梁内预留有后张预应力孔道；本申请采用正位法制作，包括以下步骤：S1，节段外模清模；S2，道岔节段箱梁钢筋入模及绑扎；S3，节段芯模吊入及调整就位；S4，道岔节段箱梁顶部钢筋吊入及绑扎；S5，节段顶模吊入，道岔钢轨槽钢模与钢轨槽钢筋对位调整固定；S6，后张预应力管道穿管并安装端模；S7，浇筑砼及抹面；S8，篷布蒸汽温控养生；S9，砼初凝后拔出后张预应力管道；S10，砼强度达到85%后拆模，脱模后继续洒水养生。本申请可生产道岔节段箱梁，利于采用节段运输，至现场拼装获得道岔箱梁；可适用于山地轨道交通等运输条件有限的情况。
